Endoscopic sinus surgery is effective to nasal sinus mucocele with eye symptoms as main manifestation. It is very importment to raise the awareness of the disease and to prompt imaging examination. Three cases were reviewed. One mucocele was found in the frontal sinus ethmoid sinus,1 in the fronto-ethmoid sinus and 1 in the spheno-ethmoid sinus. All cases were preoperatively diagnosed by CT, MRI or intranasal endoscopy. Nasal sinus mucocele with eye symptoms as main manifestation should be early diagnosed. Endoscopic sinus surgery is a safe and effective method for the treatment of nasal sinus mucocele,and could be the primary choice for it. All cases were treated by nasal endoscopic sinus surgery. The majority of symptoms, such as exophthalmos, epiphora and diplopia, disappeared in all patients. However, vision recovery was observed only in some patients.

Object To study the effects of WUZI SIWU GUASHITANG (WT) against multi glycosides of Tripterygium wilfordii Hook. f. (GTW) induced genital system toxicity in male rats and its mechanism. Methods Male rats in treatment groups were treated respectively with a 80 days oral administration of large , middle and small doses of WT plus a fixed dose of GTW. The rats as control were treated with GTW alone or saline. Thereafter, the changes in testis organ index, the number of spermatozoa, the rate of movable spermatozoa and the structure of spermatogenic cell epithlium were observed and the serum testosterone level was determined by IRMA. Then the comparison was made between treatment and control groups as to above variables. Results As compared with GTW group, large or middle dose of WT significantly increased the weight of testis, the number of spermatozoa and the rate of movable spermatozoa. Large dose of WT could relieve the damage of GTW to the spermatogenic cell epithelium completely and keep the serum testosterone at normal level. Conclusion The combined use of GTW with WT is very useful in relief of GTW induced adverse reactions of genital system in male rats. The mechanism by which WT exerts the counteractive effects is related to protecting the spermatogenic cell epithelium from being damaged by GTW, and keeping the serum testosterone at normal level.

OBJECTIVE: To investigate the feasibility and efficacy of endoscopic sinus surgery for sinonasal malignancy. METHOD: Clinical data of 40 cases of sinonasal malignancy treated in our hospital from January 2007 to December 2011 were retrospectively analyzed. The pathological types encountered were: 5 cases of malignant transformation of sinonasal inverted papilloma, 2 cases of maxillary sinus carcinoma, 3 cases of ethmoid sinus carcinoma, 11 cases of mucosal melanoma, 7 cases of olfactory neuroblastoma, 2 cases of neuroendocrine carcinoma, 4 cases of myoepithelial carcinoma, 3 cases of adenoid cystic carcinoma, 1 case of malignant hemangiopericytoma. These patients were operated on either by an exclusive endoscopic surgery or endoscopic surgery with a complementary external approach. Thirty-two patients received adjuvant radiotherapy and/or chemotherapy. RESULT: All the patients were followed up for a period of 1 to 5 years after operation, of which 18 cases survived for more than three years. Four cases recurred after six months to two years, but the result was satisfactory after revision endoscopic sinus surgery. Three cases occurred cervical lymph node metastasis, of which 2 cases received neck dissection and 1 case received chemotherapy and radiotherapy due to no surgical indications. Four cases occurred distant metastasis. Eight cases died of tumor until the last follow-up. The other 21 cases occurred no recurrence and metastasis during follow-up period. CONCLUSION Endoscopic sinus surgery is an effective method for sinonasal malignancy. Appropriate indication must be carefully selected for malignant tumor. Combined treatment based on surgery should be adopted to it.

Objective To report a case of kerion caused by Geotrichum in China. Methods A 9 year-old-boy had kerion-form lesion on his scalp with swollen posterior auricular lymph nodes, and did not show other definite underlying disease. The pathogenic fungus was identified according to culture, scanning electron microscopy, biochemical tests and DNA sequencing. The hair infection test was performed and the infected hairs were examined by scanning electron microscope. Animal test confirmed the pathogenicity of the fungus. Results The fungal colonies were the same when the tissue cultures were repeated. The colonies showed milky white to yellowish in color. The hyphae could be identified at the periphery on Sabouraud′s agar culture at 27 ℃, which were moist and smooth on the surface at 37 ℃. Under microscope, there were many rectangular arthrospores, round or oval spores with or without buddings, as well as branched hyphae. The isolated fungus was identified as a Geotrichum silvicola by culture, scanning electron microscope, biochemical test and DNA sequencing. The patient′s condition was improved markedly after treatment of terbinafine for 4 weeks. Conclusions This is the first case report of kerion caused by Geotrichum in China, and terbinafine is effective.
